Fixed support 5 is provided with optical fiber 9 inside, optical fiber 9 has good light transmission performance, can efficiently transmit the light emitted by LED lamp to subsequent light processing and detection components, sliding table fixed plate 2 side wall is provided with adjusting assembly, adjusting assembly includes manual sliding platform 3, manual sliding platform 3 side wall is slidably connected inside sliding table fixed plate 2, manual sliding platform 3 side wall is fixedly connected in fixed support 5 side wall, manual sliding platform 3 can realize accurate manual adjustment of fixed support 5 and its upper components within a certain range, by manual operation, can flexibly adjust the relative position of components such as optical fiber 9 and RGB sensor 4 according to the size, shape of different equipment to be measured and the specific position of LED lamp, so that it can accurately aim at LED lamp, improve the accuracy and reliability of detection, and manual sliding platform 3 is simple to operate, cost is lower, is suitable for the test demand of multiple different scenes, fixed support 5 side wall is fixedly connected with fixed block 11, optical fiber 9 side wall is attached inside fixed block 11, fixed block 11 provides stable mounting position and support structure for optical fiber 9, fixed block 11 side wall is screw-threaded with fixed screw 8, fixed screw 8 side wall is attached in optical fiber 9 side wall, fixed screw 8 is used for fastening optical fiber 9, by screw-threaded mode, the fastening degree of optical fiber 9 can be conveniently adjusted, fixed block 11 side wall is fixedly connected with annular light shielding silica gel 10, annular light shielding silica gel 10 inner wall is attached in one end of optical fiber 9, annular light shielding silica gel 10 can effectively block extraneous stray light from entering the receiving end of optical fiber 9, reduce the interference of external light on detection result, fixed support 5 is fixedly connected with diffusion protection plate 6 inside, diffusion protection plate 6 protects the components such as uniform light sheet 7 and optical fiber 9 inside on one hand, on the other hand, light can be diffused to a certain extent, so that light is more evenly distributed before entering uniform light sheet 7, is favorable to the further uniform treatment of light by subsequent uniform light sheet 7.The fixing support 5 is internally fixedly connected with a light uniformizing sheet 7, the side wall of the light uniformizing sheet 7 is in close contact with the side wall of the RGB sensor 4, the light uniformizing sheet 7 can uniformly process the light conducted by the optical fiber 9, so that the light is more uniformly distributed when irradiating on the RGB sensor 4, avoiding detection errors caused by uneven light, and the side wall of the optical fiber 9 is slidingly connected in the light uniformizing sheet 7. This sliding connection mode facilitates the optical fiber 9 to accurately guide the light into the light uniformizing sheet 7 for uniform processing, and is also conducive to fine adjustment of the relative position of the optical fiber 9 and the light uniformizing sheet 7 according to actual needs, further optimizing the conduction and processing effect of the light, to adapt to the detection requirements of different types of LED lamps.

[0032] First, the position of the optical fiber 9 is adjusted by the manual sliding table 3 before the test, so that the optical fiber 9 is directly opposite the center of the LED. The manually fine-adjustable feature of the manual sliding table 3 enables precise displacement operation of the fixed support 5 and the optical fiber 9 connected thereto in different spatial dimensions. The operator can flexibly change the horizontal, vertical and front-back position of the optical fiber 9 according to the specific model, size and internal LED layout of the device to be tested, so as to ensure that the optical fiber 9 can be aligned with the center of the LED at the best angle and position, and collect the light emitted by the LED to the maximum extent. When the adjustment is completed, the pneumatic cylinder 1 is started, and the pneumatic cylinder 1 drives the entire module to retreat to the test position under the control of the electromagnetic valve, so that the center of the optical fiber 9 is aligned with the center of the LED. The pneumatic cylinder 1 is responsible for stably moving the test module with the adjusted position to the preset test position, so that the relative positional relationship between the optical fiber 9 and the LED remains unchanged during the entire retreat process. At the same time, the annular light shielding silicone 10 is compressed under the action of the force of the pneumatic cylinder 1 after contacting the wall of the earphone box, and automatically forms a small dark environment. The annular light shielding silicone 10 has good flexibility and elastic deformation ability due to the silicone material, and can produce moderate compression deformation under the action of the force applied by the pneumatic cylinder 1 when the pneumatic cylinder 1 pushes the test module to approach the earphone box and other devices to be tested, so that the annular light shielding silicone 10 contacts the wall of the device. This effectively fills the possible gaps and prevents the penetration of external environmental light. Moreover, the light shielding property of the silicone itself can ensure that a relatively independent, dark and stable light test environment is formed in the space surrounded by the silicone, which greatly reduces the interference of external stray light on the light emitted by the LED, improves the detection accuracy and reliability, and transmits the light emitted by the LED to the light uniformizing sheet 7 through the optical fiber 9. The optical fiber 9 can efficiently transmit the light emitted by the LED to the light uniformizing sheet 7 with extremely low loss by virtue of its special optical structure and material properties. After passing through the light uniformizing sheet 7, the light is uniformly irradiated on the light sensing chip above the detection panel of the RGB sensor 4. The light uniformizing sheet 7 can effectively homogenize the light transmitted by the optical fiber 9, so that the light presents uniform intensity distribution and angle distribution when reaching the light sensing chip on the detection panel of the RGB sensor 4. This uniform light irradiation can ensure that each sensing area of the light sensing chip receives light signals of the same quality and intensity, avoiding local sensing deviation caused by uneven light, thereby significantly improving the accuracy and stability of the RGB sensor 4 in detecting the color and intensity of the light. After sensing, the light sensing chip automatically analyzes and detects the color and flashing times of the light, and then feeds back these parameters to the center of the entire test system to judge whether the LED function is detected normally. The light sensing chip on the detection panel of the RGB sensor 4 serves as the core photoelectric conversion and analysis element, and can quickly and accurately convert the received light signals into electrical signals.It has high sensitivity distinguishing ability to different wavelength light, can accurately identify the proportion and intensity change of red, green and blue three basic color components in light, thereby accurately distinguishing the color characteristics of light. Meanwhile, the light sensing chip can also accurately count the number and frequency of light flicker by monitoring and analyzing the change of light signal intensity with time. Then, the light sensing chip rapidly feeds back these detected key parameters such as color and flicker number to the whole test system center in the form of electrical signal, and the test system comprehensively analyzes and compares these parameters according to the pre-set standards and algorithms, thereby accurately judging whether the LED lamp meets the corresponding design requirements and quality standards in color display and flicker function, and realizing the comprehensive and efficient detection of LED function.

[0033] Working principle: first, adjust the position of the optical fiber 9 by the manual sliding table 3 before testing, so that the optical fiber 9 is directly opposite to the center of the LED, when the adjustment is completed, start the air cylinder 1, the air cylinder 1 drives the whole module to retreat to the test position under the control of the electromagnetic valve, the center of the optical fiber 9 is aligned with the center of the LED, at the same time, the annular light shielding silica gel 10 is compressed under the action of the air cylinder 1 after contacting the earphone box wall, and a small dark environment is automatically formed, the light emitted by the LED is conducted to the light uniforming sheet 7 through the optical fiber 9, after passing through the light uniforming sheet 7, the light is uniformly irradiated on the light sensing chip on the detection plate of the RGB sensor 4, the light sensing chip senses and automatically analyzes and detects the color and the number of flicker of the light, and then feeds back these parameters to the whole test system center to judge whether the LED function is normal.
